This sounds like a problem with your sound card or drivers. Are you able to hear sound in other applications (games etc..).

If not access the device manager by:

- Right click 'My Computer'
- Select the 'Harware' tab
- Click 'Device Manager'

Scroll down the list to see if there are any with yellow or red icons next to them. If there are double click them and look at the device status.
